According to Osho, Zen is indeed the path of surrender—understood not as yielding to an external authority, but as inner relaxation and trust. Like a skilled swimmer who becomes one with the river, you stop fighting life and flow with it. God or objects of devotion are unnecessary; surrender is an attitude, not a belief: relax, accept, and live through direct trust rather than mental “belief.”
Yes: Zen means stop struggling and trust life, like floating in a river instead of fighting the water.
